WASP-36

WASP-36 is a astronomy topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand WASP-36 rather than just read about it. In short: WASP-36 is a G-type main-sequence star about 1,230 light-years away in the Hydra constellation. Star characteristics WASP-36 is a yellow main sequence star of spectral class G2, similar to the Sun.

Key takeaways

WASP-36 belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect WASP-36 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of WASP-36 from memory before moving on to harder problems.

Reference excerpt

WASP-36 is a G-type main-sequence star about 1,230 light-years away in the Hydra constellation.

Star characteristics WASP-36 is a yellow main sequence star of spectral class G2, similar to the Sun. It has a candidate stellar companion with apparent magnitude 14.03, seemingly confirmed in 2019 using Gaia DR2 data.

Planetary system In 2010, the SuperWASP survey found the hot Jupiter class planet WASP-36b using the transit method. Its temperature was measured to be 1705±44 K. The planetary transmission spectrum taken in 2016 has turned out to be anomalous: the planet appears to be surrounded by a blue-tinted halo that is too wide to be an atmosphere and may represent a measurement error. The planetary dayside temperature measured in 2020 is 1440+150−160 K.

Worked examples

Example 1 — a first encounter with WASP-36

Start with the simplest possible case. Write down what WASP-36 claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to WASP-36 before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about WASP-36 ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of WASP-36

In research: WASP-36 appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses WASP-36 in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: WASP-36 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Binary stars, G-type main-sequence stars, Hydra (constellation), so understanding it makes those chapters shorter.
In everyday life: Look for WASP-36 outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
